If you are receiving a message stating that you have exceeded the number of ACT installations available, this is because you are trying to setup ACT on an additional site other than the URL you originally installed ACT on.

You can either purchase another license for $99/month subscription, or you can migrate your ACT from your previous site to the new one you are trying to setup.

If you do not have ACT installed anywhere yet and are getting this error message, please submit a support ticket.
